New search warrants related to missing teens unsealed

(KUTV) — Two additional search warrants out of Sanpete County, unsealed Wednesday, show investigators have obtained cell phone records and Facebook profile information from a number of people in relation to the disappearance of Breezy Otteson (18) and Riley Powell (18).

The couple disappeared in late December while traveling from Tooele to Eureka. They were officially reported missing on January 2nd.

The new information shows police requested 79 days' worth of phone records from mobiles belonging to Otteson, Powell and Powell's mother, Mistie Carlson. Police obtained those records on the belief they would find evidence of illegal conduct, pertinent to a murder investigation.

In addition to all calls and texts made between 11/01/17 and 01/18/18, police also requested any emails associated with the cell phones that might lead to, for example, a Google or iTunes account.

A second warrant was issued for detectives to obtain Facebook profiles from Riley Powell, Mistie Carlon, and Lee Shepherd. In a sworn affidavit, detectives say multiple conversations were previously found on Otteson and Powell's Facebook pages - with multiple people in Juab and Tooele Counties. All conversations seem to end on the night of the 29th of December, or the morning of the 30th.

The new information also shows that when police executed a search warrant at the home of Mistie Carlson on January 16th, neither she, her boyfriend, Lee Shephard, nor her mother, Linda Powell, were at home. Linda Powell's boyfriend, William Larson, according to the affidavit, told police all three were in Wendover. Two days later, detectives were informed by West Wendover police, that Carlson had attempted suicide and had been taken to the University of Utah hospital.

During the January 16th search of the home, the affidavit says cadaver dogs were particularly interested in Lee Shepherd's blue Chevy truck. It was then taken into evidence.
